Soap that cleans the climate: How we capture carbon directly from the air

Here is a little insight into how we use atmospheric carbon to create the key ingredient for our natural, handcrafted soaps.

Preparing a potassium hydroxid solution for direct air capture

Setting the stage

First, we prepare a solution of pure potassium hydroxide and distilled water. Think of it as the "net" we use to catch the carbon.

The magic moment: Direct Air Capture

This is where it gets exciting: we spread our solution thinly across large trays. In a natural process at room temperature, the liquid gradually reacts with the carbon dioxide (CO₂) in the ambient air, crystallising into solid potassium carbonate salt.

Patience and timing

We then let the air and time do their work. Depending on the temperature, humidity, and the carbon levels in the air, it takes one to two days for the solution to reach the perfect concentration. Only when the quality is spot on do we begin our "carbon harvest".

Skin care, planet in mind

Once harvested, the potassium carbonate is filtered to ensure purity. It is then ready to be used in our natural soap recipes, where it creates an exceptionally rich lather and a silky-soft feel on your skin.
